python xml parsing

import xml.etree.ElementTree as ET
tree = ET.parse('train_11pts.xml')
rt = tree.getroot()
# 根据路径解析 ./images/image
im = rt.findall('./images/image')
b = imgs[0].find('./box')
print len(b)
# 列出b的子元素
# list(b) , b.items()
print b[0].attrib
# {'name': '00', 'x': '66', 'y': '182'}
# 获取某个属性
print b[0].attrib['name']
